Cogito Ergo Nomics

cogito ergo nomics

How easy is your car to use? I'm not talking about acceleration, steering or cornering. I'm talking about the mental effort required to successfully interact with your car’s secondary features, such as in-car entertainment or the trip computer. While controls like steering (the brilliant simplicity of a wheel), throttle (foot pedal farthest to the right) and braking (second-to-right pedal) are standardized for most vehicles certified for use on a public road, the majority of other controls are confusing enough to plunge an automotive reviewer (or a Hertz Platinum Club member) into RTFM rage.

Sometimes it’s a simple matter of old habits dying hard: in many ways the best interface is one you don't have to re-learn. If you're used to having to jab at a button several times to adjust the temperature several degrees while surveying the change on a display that’s located on the opposite hemisphere of the dash, that may be the best user interface—for you.

But that’s not the whole story when something as basic as starting the car has now taken on innumerous forms. Do you A) insert the key in a slot (to the right or left of the steering wheel or in the center console) and turn it or B) insert the key in a hole and push it or C) insert the key into a slot and push a start button or D) ignore the key altogether as long as it's on your person and then either push a button or twist a piece of plastic adjacent to the steering wheel? Each of these methods are used by at least one current production car—and I’m sure I’ve missed at least one type of ignition sequence.

Changing gears is a similar issue. If you want to upshift using an automatic transmission with a shift-it-yourself mode, do you tap the shifter forward, backward or to the right? Or do you use buttons on the steering wheel? If you use steering wheel buttons, do you push the button on the right to upshift or on the back to downshift and the front to upshift? Or does the car instead use paddles behind the steering wheel? Which paddle do you use? Do you push or pull? And in case you want to shift while turning, do the paddles rotate with the steering wheel or are they stationary?

Even something as simple as automatic door locks come complete with their own set of usability issues. Do they lock when you put the car in Drive or when you reach a preset speed? Do they automatically unlock when you put the car back in Park? Do they automatically unlock when you pull the interior door handle, and if so, in the back seat or just the front? How do you disable them? Can you disable them? Can you even answer these questions about your own car?

Clearly, usability and interface design principles are taking a backseat to aesthetics and automakers’ oddly conflicting compulsions to be both trendy and unique. The problem is compounded by the unprecedented numbers of features being added to new cars, such as satellite radio and navigation, iPod integration, DVD players, Bluetooth cell phone connections, four-zone climate control, OnStar, heated and cooled massaging memory seats, etc. Without well-thought-out ways of interacting with these new features, the result is anarchy. I’d like to know how many times BMW Assist has been summoned by X5 drivers who thought they were opening their sunroofs, since the corresponding buttons are poorly marked, nearly identical, and adjacent to each other in matching wells, for no apparent reason other than BMW’s ever-questionable ideas regarding aesthetics.

Annoyances aside, this is a serious matter. Among products that most of us deal with on a day-to-day basis, cars inhabit a special subcategory: products that regularly cause death. Anything that requires us to dawdle too long with an in-car interface literally puts lives in danger, yet cars are still often poorly thought out or designed with form over function. No matter your opinion on how easy BMW’s iDrive controller is to learn, there’s no getting around the fact that you have to take your eyes off the road for significant periods of time to navigate through its seemingly endless hierarchy of menus.

While manufacturers may be aware of the problem, they’re not very good at solving it. They often seem to simply compete in shoehorning more features into fewer buttons, birthing such disastrous ideas as the aforementioned 11-way haptic feedback control knob (a.k.a. iDrive) and nearly equally—though differently—awful in-car voice recognition. For enthusiasts, these issues are particularly pressing. Any device which gets between them and driving is, rightly, reviled. Any device that adds to their enjoyment without frustrating them is celebrated. For hi-tech-loving manufacturers, designing a car that’s easy-to-use that pleases the cognoscenti isn’t proving easy.

  • GregLocock Two adjacent states in Australia have different attitudes to roadworthy inspections. In NSW they are annual. In Victoria they only occur at change of ownership. As you'd expect this leads to many people in Vic keeping their old car.So if the worrywarts are correct Victoria's roads would be full of beaten up cars and so have a high accident rate compared with NSW. Oh well, the stats don't agree.
  • Lorenzo In Massachusetts, they used to require an inspection every 6 months, checking your brake lights, turn signals, horn, and headlight alignment, for two bucks.Now I get an "inspection" every two years in California, and all they check is the smog. MAYBE they notice the tire tread, squeaky brakes, or steering when they drive it into the bay, but all they check is the smog equipment and tailpipe emissions.For all they would know, the headlights, horn, and turn signals might not work, and the car has a "speed wobble" at 45 mph. AFAIK, they don't even check EVs.
  • Not Tire shop mechanic tugging on my wheel after I complained of grinding noise didn’t catch that the ball joint was failing. Subsequently failed to prevent the catastrophic failure of the ball joint and separation of the steering knuckle from the car! I’ve never lived in a state that required annual inspection, but can’t say that having the requirement has any bearing on improving safety given my experience with mechanics…
  • Mike978 Wow 700 days even with the recent car shortages.
  • Lorenzo The other automakers are putting silly horsepower into the few RWD vehicles they have, just as Stellantis is about to kill off the most appropriate vehicles for that much horsepower. Somehow, I get the impression the OTHER Carlos, Tavares, not Ghosn, doesn't have a firm grasp of the American market.
